The probability that two of the coins will be tails is 1/2
It is 1/2 because "at least two tails" means that two tails and the rest of the number of tails, which is 3. In total the three coins have 6 sides. The chance of having two tails and one is three out of 6, simplified is 1/2 ;)
Answer:
In example when talking about some supply, half of it was sold or three fifths of what was there is gone. Fractions are a natural way of talking about sub unit quantities or just rationing supplies.
Answer:
2000 bars, or $1200
Explanation:
Let x represent the number of candy bars that are sold. Since they are sold for $0.60 each, this gives us the expression
0.60x
to represent the profit.
The factor has $0.10 per candy bar additional expense; this gives us the expression
0.10x.
However the factory also has $1000 fixed costs; this gives us
0.10x + 1000
to represent the costs.
The break-even point is the point where these two expressions are equal; this gives us the equation
0.60x = 0.10x + 1000
Subtract 0.10x from each side:
0.60x - 0.10x = 0.10x + 1000 - 0.10x
0.50x = 1000
Divide both sides by 0.50:
0.50x/0.50 = 1000/0.50
x = 2000
The break-even point is 2000 candy bars, which would sell for
0.60(2000) = $1200
a farmer grows 128 red tomato plant produces about 32 tomatoes
Each tomato plant produces 32 tomatoes
Total number of tomatoes produced = 128 * 32 =4096 tomatoes
the farmer plans to sell each tomato for 2.00.
Each tomato cost = $2
4096 tomatoes cost = 2 * 4096 = $8192
the farmer will earn $8192 if she sells all of the tomatoes
